Abstract
This paper resents a theoretical analysis for the grounding impedance influenced by the ground rod's dimension using the distributed parameter model. In this paper, EMTP and Matlab Program were used to simulate the distributed parameter model and to analyze the frequency-dependent characteristics of the ground rods. We compared two kinds of ground rods having different dimensions and the frequency-dependent characteristics of two ground rods were quite different from each other. It is estimated that these different characteristics are caused by the distributed parmeters which are changed by the length of ground rod.
